The cathode current is 65 µA, representing the minimum bias current needed to keep the reference in its operating region — important for power-constrained designs where every microamp counts. ## 150 ppm/°C drift and 20 µVrms noise Noise from 10 Hz to 10 kHz is 20 µVrms, low enough for most 12-bit ADC references but worth checking if the design targets 16-bit or higher resolution without additional filtering. For new designs or volume production, the LM4041AIM7-1.2 (same fixed 1.225V, tighter ±0.1% tolerance, same SC-70-5 footprint) is a common cross-shop candidate — confirm the tolerance grade matches your BOM before substituting.","metaTitle":"LM4041EIM7X-1.2 Shunt Voltage Reference, 1.225V Fixed, ±2%","metaDescription":"LM4041EIM7X-1.2 precision shunt reference, 1.225V fixed output, ±2% tolerance, 12 mA output, SC-70-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"65 µA","Base Product Number":"LM4041","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SC-70-5","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/26af4fd2ab0c421228a4f1c33eae6ec2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041EIM7X-1.2/alternatives.json"},"ai":{"faq":[{"question":"Is LM4041EIM7X-1.2 equivalent to LM4041AIM7-1.2?","answer":"Both parts share the same fixed 1.225V output and SC-70-5 package, but the LM4041AIM7-1.2 carries a tighter ±0.1% tolerance versus the ±2% grade of the LM4041EIM7X-1.2.
